From the manufacturer

Lightweight and compact, the Distance LT 1100 is built to shine on pre-dawn-to-dark endurance days, where every ounce counts. 

The bounce-free design features a slim, pivoting lens assembly, while the main rechargeable battery housing remains fixed and stable against the headband. The integrated PowerTap™ Technology temporarily boosts the light to 1100 lumens with a simple tap for long-range viewing, and automatically dims after 10 seconds to conserve battery life. The Distance’s engineered lens design maintains broad, diffuse lighting and depth perception through the range of brightness levels.
